I've installed a new UTS and I still have the same issue. I also
obtained a serial port slot plate adapter for the on-board COM port
on the motherboard and tried that. I still have the same issue with it.
Now, this really is new and I haven't the faintest idea what's
happening. It's as if the DTR line (which is what the RigBlaster uses
for PTT) is being polled. But it's being polled even through the
on-board COM port (which I assume really is a 16650 UART).
When I start any program that uses the assigned com port (COM2 if it
matters) for PTT, such as MMTTY, HamScope or WinPSK, the polling
behavior stops. When I use any of these, I go through EXTFSK (v1.06).
If I go through the hardware manager and disable the port, the
polling behavior stops. But, as soon as I enable the port, the
polling behavior recommences.
Has anyone ever seen behavior like this? If you did, how did you
solve it? I'm using XP SP3...
